| participation of endothelial cells in murine schistosomiasis. | the endothelial cells participate in the morphological events occurring during murine schistosomiasis, taking part in the development of hepatic periovular granuloma. the cells also show an increase in the expression of factor viii-related antigen in the portal vessels and hepatic sinusoids during the infection. endothelial cells are suggested to play an important role in the pathogenesis of the disease and in the balance of the coagulant-anticoagulant mechanisms which favor the intravascular su ... | 2011 | 3150298 |
| single unit response of suprachiasmatic neurons to arginine vasopressin (avp) is mediated by a v1-like receptor in the hamster. | a large population of local circuit neurons within the suprachiasmatic nucleus (scn) exhibit immunopositive staining for arginine-vasopressin (avp). avp has been reported to be released from scn neurons in a circadian pattern that peaks during the subjective day. using an in vitro hypothalamic slice preparation, the present study investigated how scn neurons respond to avp over the circadian cycle and whether the response to avp is mediated by v1- or v2-like avp receptors. exposure of the slice ... | 2009 | 2702494 |
| nephrotoxic drugs. | the nephrotoxic effects of cyclosporine, aminoglycoside antibiotics, cisplatin, amphotericin b, beta-lactam antibiotics and indomethacin are reviewed. these drugs were chosen because they are among the most frequent causes of renal injury in children. in addition, their nephrotoxicity is caused by different mechanisms. several generalizations can be made, however. first, agents which cause tubular damage tend to be synergistic in their toxic effects. this synergism is seen when several nephrotox ... | 2011 | 3153061 |

| [ecg changes in chronic polyarthritis compared to a healthy control group]. | ecg from 200 patients with radiologically and clinically definite rheumatoid arthritis were compared with those from a healthy group with the same age and sex distribution. the frequency of pathological changes of the ecg was found to be the same in both groups. therefore doubt remains whether the pathological changes of the ecg can be attributed to rheumatoid arthritis. | 2000 | 92110 |

| imipramine in absence and myoclonic-astatic seizures. | a double-blind crossover study with imipramine was conducted in 10 patients with absence and myoclonic-astatic seizures who had not responded to conventional medications. imipramine produced a significant initial decrease in seizure frequency in 5 of the 10 patients, and in 2 patients the beneficial effect was maintained for more than 1 year. an open trial of imipramine in another 16 patients showed an initial reduction in seizure frequency in 10 patients (63 percent), and this decrease persiste ... | 2001 | 99690 |

| [anomalous branching of the inferior thyroid artery from the left vertebral artery]. | in a 53 years old woman hospitalized for a suddenly developed picture of vascular insufficiency in the verterobrobasillary vascular bed the authors detected an anomalous division of the left vertebral artery from aortic arch. moreover, at the level of thyroid gland there was the division of inferior thyroid artery from the vertebral artery. we express the opinion that the finding did not participate in the clinical symptomatology. | 2006 | 2225222 |
| heavy- and free light-chain myeloma associated with peripheral polyneuropathy. | peripheral polyneuropathy, a rare complication of multiple myeloma, is generally associated with heavy-chain m-proteins and, in very rare instances, with free light-chain myeloma proteins. here we describe a case of multiple myeloma and polyneuropathy with both monoclonal igg and free lambda light chains in the blood. the patient also had free lambda light chains in the cerebrospinal fluid and urine. | 2010 | 2848651 |

| why aged men become impotent. | despite frequent erectile impotence in aged men, etiologic data are scarce. we evaluated 121 impotent male veterans (mean age, 68 +/- 5.3 years) to obtain information on potential pathophysiologic mechanisms. subjects related a complete medical history and underwent physical examination, metabolic assessment, nocturnal penile tumescence monitoring, and vascular and neurologic assessment. the most frequent cause of impotence was the coexistence of neurologic and vascular disorders (30.3%). other ... | 2009 | 2786397 |

| subaortic aneurysm of the left ventricle. | a subaortic aneurysm of the left ventricle resulting in massive hemopericardium is described. the anatomy of the aortic anulus, aortic valve, and pericardial reflections at the base of the heart are constructed in a manner that allows the migration of blood from the left ventricle, through an area of aortic anular dehiscence, resulting in the formation of a false aneurysm. the pertinent anatomy is described, as well as pathogenesis and similar cases in the literature. | 2011 | 3207485 |
